Google Chrome Developer Tools: search for exact match

How can I search for some text that has spaces in it in all JavaScript sources on website?
I know that I should use "CTRL + SHIFT + F"(on Windows), but Google Chrome Developer Tools searches not for the whole sentence, but for each word that is separated by space.
How to find exactly what I've typed into searchbox ?

Please see screenshot:

Is it a bug in Chrome version "33.0.1750.117" ? It worked ok previously... Is there a workaround?
